The laser processing technology is based on lasers, so it is explained below in terms of the composition of lasers, the characteristics of various lasers, and the optical systems for laser processing, laser dies and abandonment devices, laser parameter measurement, and laser and material interaction mechanisms. Laser processing technology.
Laser bending is a new flexible forming technology. It uses the uneven temperature field generated by laser heating to induce heat stress instead of external force to achieve the metal sheet molding. The laser forming mechanism includes a temperature gradient mechanism, a buckling mechanism, and a roughening mechanism. Compared with the flame bending, the laser beam can be confined in a very narrow area and can be easily automated. This has led to people's interest in laser bending. At present, there are some successful examples of this technology research, such as the bending of ship plates, the use of laser bending of tubes to make indium to manufacture bellows, and micromachining.
There are many types of lasers used for laser processing, and new lasers have also been developed. Lasers currently used in laser processing and manufacturing include 602 lasers, v80 lasers, excimer lasers, high-power semiconductor switches, and fiber lasers. Among them, high-power 002 lasers and lasers are widely used in laser processing technology of large-swing workpieces; å±® small-power 002 lasers; lasers are used in precision machining; excimer lasers are often used in micro-machining; and ultra-short pulses (flying) Seconds) Compared with the thermal diffusion of lasers and materials, they can be injected into the irradiation site more quickly, so they are mainly used in the processing of ultra-fine cutting machines; semiconductor lasers are lasers with the smallest volume of all lasers. Laser storage, laser ranging, laser printing and other aspects have been widely used; fiber-based fiber lasers have obvious advantages in reducing the threshold, oscillation wavelength range, wavelength tunable performance, etc., and have become the current emerging in the laser field. Technology is also hot.
In short, laser processing technology is an advanced manufacturing technology in the 21st century, and its development prospects are limitless. However, laser processing technology is still a developing technology, and it is not yet mature. It is not like the traditional processing of cold processing vehicles, drilling, milling, planing, grinding, but also + heat processing forging, casting, welding, Jin Li heat treatment and so on. The whole set of metal technology theory and standardized process. In laser processing applications, especially in the application process of laser cutting technology described in this book, practice and experience are bound to be numerous. When designing and manufacturing specialized equipment for specific application objects and requirements, it is necessary to fully investigate, study, and absorb the experience of previous generations. Even using the more general laser processing equipment currently sold in the market, it is necessary to fully test the processing of the parts and components that are processed, and to establish and improve the theory and specifications of laser processing technology in practice.
